Proposal

Write a code gen tool for wrapping a specific function signature in a struct, that implements an interface which labassistant uses to create and run new experiments.

Status

Unfinished draft.

Pros

• Not having to do dangerous reflect magic and be able to use strongly typed code.
• No reflect magic means less code to run, therefor speed boost?

Cons

• Yet another tool to run.
• More code the user has to manage himself.

Design

Run nameoftool "GoFunctionSignature" and it prints generated code to stdout.

Example code to be generated (WORK IN PROGRESS):

struct exampleWrapper {
    f func(arg1, arg2, etc...) (out1, out2, etc..)
}

NewWrapper(f func(args...) (outs...)){
    wrapper = new exampleWrapper
    wrapper.f = f
    return wrapper
}

// Implements a funcWrapper interface, to be added to the labassistant library?
wrapper.Run(arg1, arg2, etc...){
    outs = wrapper.f(arg1, arg2, etc..)
    return outs
}
